IMPROVEMENT N CH URNS.

Specification forming part of Letters Patent No. 4 LEWQ, dated January 19, 1864.

To It whom it may concern:

Be it known that 1, DANIEL K. PRICE, of Ossian, in, the county of Livingston and State of New York, have invented a new and useful Improvement in Ghurns and Ido hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, making part of this specification.

Figure 1 is a central vertical section of my improved churn; Fig. 2, a front elevation of the partition 5 Fig. 3, an enlarged perspective view of one of the dashers.

Like letters of reference indicate corresponding parts in all the figures.

My invention consists in a box provided with a central partition, having an inclined dasher on each side, said dashers being connected with an operating-lever and adjustable up and down to adapt them to any amount of cream to be churned at once.

A box, A, is provided, preferably rectangular or square in cross-section, having a central groove, c, on two opposite sides, in which groove slides a vertical partition, 13. The bottom portion of the partition is perforated or covered with a wire screen, I), which insures a communication between the two compartments O O of the churn. In these-compartments, respectively, play dashers or pistons D D, filling the entire space. They are fastened to dasher-rods E E, extending upward through the cover G and secured to rigid elbows H H, stifilybraced by iron braces c c, said elbows in turn being jointed to an operating-lever, I, which vibrates on a central pivot, d, in a standard, K. The top of the standard is provided with a set of vertical adjusting-holes, fff, for raisin g or lowering the lever, and the upper end of the elbows are also provided with similar adjusting-holes, g g g, for raising or lowering the dashers.

The dashers are inclined from the center downward and backward, as clearly represented in Fig. 1, and they are provided on the back or outer side with holes h h, Fig. 3.

There are several distinct advantages resulting from this arrangement.

First. The partition B, by being provided with the fine meshes b, cuts the cream up more thoroughly in its reciprocations from one compartment to the other than could be done b any other arrangement of perforations 0 holes. Being so fine, the meshes effectively separate and break the globules of the cream.

Second. The dashers, by being inclined in the direction indicated, have a tendency to throw the cream more forcibly inward through the partition than they would if perfectly horizontal, and therefore lessen the power necessary to apply in operating thechurn, and produce a greater f1 iction and action of the cream. The peculiar arrangement of the dasbers also produces an action or motion of the cream, secondary or additional to s reciprocations from one compartment. to the other-viz: At the commencement of the upward stroke of either dasher, the incline throws the cream backward, and it runs down through the holes h h by the force of gravity, as indicated by the red arrow at the right in Fig. 1. The cream thus describes a circuit, as it were, around the dashers, passing inward at the downward stroke and outward at the upward stroke.

Third. The use of the elbows H H enables me to attain the proper length of stroke without an undue vibration of the operating-lever, while the dashers are as easily operated and guided as if the dashcr-rod connected directly with the lever.

Fourth. By the use of the adjustable holes ff in the top of the supporting-standard, the lever can be raised or lowered to adapt it to the height of the .pcrson operating it, or to accommodate any circumstances that may require an adjustment, while at the same time the holes 9 g in the ends of the elbows allow the dashers to be adjusted to any such change of the operating-lever, or to the amount of cream to be churned at once.

I do not claim, broadly, a central partition, with dashers reciprocating on either side, nor do I claim separately any of the parts herein described; but

W hat I claim as my invention, and desire to secure by Letters Patent, is-

The arrangement of the reciprocating dashers D 1), made inclined for the purpose of throwing the cream forward through the partition, and provided with holes h h in the rear for throwing the cream backward when it is raised, the central perforated wire partition, 13, for thoroughly breaking the cream, and the adjustable elbows H H, for increasing the length of the stroke without increasing the vibration of the lever, when the said parts are combined with the box A, lever I, and'standand K, substantially as herein set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

DANIEL K. PRICE.
